Rear Window Wiper Jeep Grand Cherokee: Ultimate Replacement Guide
Reading Time: 8 minutes The rear window wiper on the Jeep Grand Cherokee is a small feature, but it plays a big role in driving safety. Many Jeep owners only notice this wiper when it stops working, or when weather turns bad. In reality, understanding how this wiper works—and how to keep it in good shape—can save you from common problems and help you drive more safely in rain, snow, or dust. If you are new to car maintenance, or this is your first SUV, don’t worry. This guide will explain everything in simple terms.
What Is A Rear Window Wiper?
The rear window wiper is a moving blade attached to the back window of your Jeep Grand Cherokee. Its main job is to clear water, snow, or dirt so you can see clearly out the back. This is important for reversing, parking, and driving in bad weather. Unlike front wipers, the rear wiper only covers the back glass. It’s controlled by a switch inside the car—usually on your wiper control stalk.
Why Rear Wipers Matter
- Better visibility: Clears rain and dirt for a safer drive.
- Essential for SUVs: SUVs like the Grand Cherokee have almost flat rear windows. Water and dust do not slide off as easily as on sloped windows.
- Helpful in winter: Melts and clears snow or frost, making it easier to drive and park.
Many drivers forget to use or check their rear wiper until it fails. But it’s just as important as your front wipers—especially during heavy rain or on muddy roads.
How The Rear Wiper System Works
The rear wiper on a Jeep Grand Cherokee is a simple but smart system. It includes several main parts:
- Wiper arm: The metal part that holds the blade.
- Wiper blade: The rubber part that wipes the glass.
- Electric motor: Powers the arm to move back and forth.
- Washer nozzle: Sprays cleaning fluid onto the glass.
Here’s a quick look at how these parts work together:
- You turn on the rear wiper from inside the cabin.
- The electric motor moves the wiper arm.
- The blade presses against the window and wipes away water or dirt.
- If you use the washer, fluid sprays onto the glass and the wiper clears it.
Many Jeep Grand Cherokees have a single rear wiper that sweeps a half-circle. The washer fluid helps remove sticky dirt or bird droppings.
Common Rear Wiper Problems
Even though the rear wiper is simple, it can develop problems over time. Here are some common issues:
- Wiper not moving: Usually caused by a failed motor, broken fuse, or electrical problem.
- Wiper blade streaking: The rubber is old or cracked and does not clear well.
- No washer fluid: The nozzle is clogged, or the fluid tank is empty.
- Wiper arm stuck: Ice, snow, or dirt can block the movement.
Example
Suppose your rear wiper does not move at all. First, check the fuse box (usually under the hood or dashboard). If the fuse is blown, replace it. If the wiper still does not work, the motor may need replacement.
How To Replace The Rear Wiper Blade (step-by-step)
Changing the rear wiper blade on a Jeep Grand Cherokee is easy. You don’t need special tools, and it only takes about 5 minutes.
What You Need
- New rear wiper blade (usually 12-14 inches for Grand Cherokee; check your manual)
- Clean cloth
Steps
- Lift the wiper arm: Gently pull the arm away from the glass until it locks in a raised position.
- Remove the old blade: Find the small tab where the blade meets the arm. Press the tab and slide the blade off.
- Attach the new blade: Slide the new blade onto the arm until it clicks.
- Lower the arm: Carefully place the arm back onto the window.
Practical Tips
- Don’t let the wiper arm snap back on the glass—it can crack the window.
- Wipe the window clean before installing the new blade.
- Always buy the correct size for your Jeep model.

Rear Wiper Motor: When And Why To Replace
The rear wiper motor is the small electric part that moves the wiper arm. Over time, it can wear out due to use, weather, or electrical problems.
Signs Your Motor Is Failing
- Wiper moves slowly or with a grinding sound.
- Wiper stops in the wrong position.
- Wiper does not move at all, but the fuse is fine.
Cost And Replacement
Replacing a rear wiper motor usually costs between $100 and $250 for parts and labor. You can do it yourself if you have basic tools, but many people prefer a mechanic. The part is usually behind the rear window trim.
Example: Diy Or Mechanic?
If you enjoy simple car repairs, you can save money by buying a motor and installing it at home. Otherwise, a certified shop can do the work in about an hour.
Rear Wiper Blade Comparison: Oem Vs. Aftermarket
You can choose between OEM (Original Equipment Manufacturer) and aftermarket rear wiper blades. Here’s how they compare:
| Feature | OEM Blade | Aftermarket Blade |
|---|---|---|
| Fit | Perfect, made for Jeep | May require adjustment |
| Price | More expensive | Usually cheaper |
| Quality | Consistent, reliable | Varies by brand |
| Warranty | Comes with Jeep warranty | Brand warranty only |
Key Insight
Many beginners think any blade will work. But buying the wrong size or attachment style can make the wiper loose, noisy, or even fall off. Always check your owner’s manual or ask an expert before buying.
Rear Wiper Maintenance Tips
To keep your rear window wiper working well, follow these simple tips:
- Clean the blade with a damp cloth every few weeks.
- Replace the blade every 6-12 months, or if you see streaks or hear squeaking.
- Check washer fluid often, especially before long trips.
- Clear ice or snow by hand before using the wiper in winter.
Common Mistake
Never use your wiper to clear thick ice. This can burn out the motor or break the blade.
Jeep Grand Cherokee Rear Wiper Compatibility (year-by-year)
Different Jeep Grand Cherokee models use different wiper blade sizes and styles. Here’s a quick guide:
| Model Year | Rear Wiper Blade Size | Attachment Type |
|---|---|---|
| 2011–2021 | 12 inches | Hook or pinch tab |
| 2005–2010 | 13 inches | Hook |
| 1999–2004 | 14 inches | Hook |
Always double-check your Jeep’s manual before buying, as some trims and special editions may be different.
When To Use The Rear Wiper
Many drivers are unsure when to use the rear wiper. Here are the most common situations:
- Rain: Use for clear vision out the back.
- Snow or frost: Use after scraping ice from the window.
- Dust or mud: Use with washer fluid to remove dirt.
- Parking: Clear the window before backing up.
Non-obvious Insight
On highways, dirty spray from other cars can quickly block your rear view. Using the wiper and washer fluid together keeps your window clear and safe.
Rear Wiper Vs. Rear Defroster
Some new Jeep owners confuse the rear wiper with the rear defroster. These are two different features:
- Rear wiper: Moves to clean water, dirt, or snow.
- Rear defroster: Heats up lines on the glass to melt frost or ice.
You can use both at the same time for best results in winter.

Choosing The Right Rear Wiper Blade

Environmental Impact And Recycling

Frequently Asked Questions
How Often Should I Replace The Rear Wiper Blade On My Jeep Grand Cherokee?
Most experts recommend replacing the rear wiper blade every 6 to 12 months. If you see streaks, hear noise, or notice the rubber is cracked, change it sooner.
Why Is My Rear Wiper Not Working Even After I Changed The Blade?
If a new blade does not fix the problem, check the fuse, wiring, and the wiper motor. Sometimes the motor fails or the wiring gets damaged. If you’re unsure, have a mechanic check the system.
Can I Use The Same Wiper Blade As The Front On The Rear Window?
No. Front and rear wiper blades are different sizes and shapes. The rear wiper is usually shorter and has a different attachment. Always buy the correct blade for the rear window.
Does The Rear Wiper Use The Same Washer Fluid As The Front?
Yes, the washer fluid tank usually supplies both front and rear wipers. But the rear nozzle and lines can get clogged, so check for blockages if no fluid sprays out.
How Do I Prevent My Rear Wiper From Freezing In Winter?
Before using the rear wiper, clear off heavy ice and snow by hand. You can also use the rear defroster to melt ice before using the wiper. Never force the wiper if it’s frozen to the glass.
Driving with a clear rear window keeps you safer and makes your Jeep Grand Cherokee more enjoyable in all weather. Paying a little attention to your rear wiper—choosing the right parts, keeping it clean, and replacing it as needed—pays off every time you hit the road.
